I am having trouble deciding between the following sizes for Michelin Pilot Sport 4S's:

Front- 285/35/20
Rear- 295/35/20

or

Front- 295/35/20
Rear- 305/35/20

I have stock m5 competition wheels, it is lowered on 550 H&R springs and I have 12mm spacers rear and 15mm spacers in the front.


I read the post where HiggsBoson is lowered on Eibach Springs with:

Michelin PS4
295/35/20
305/35/20

Wheels are the Titan7
20x11 +22
20x12 +30

Front pushes out 16mm vs stock
Rear pushes out 8mm vs stock

Which is pretty close to where I would be with +12 and +15, so my rear would only be 4mm out further than him where he ran 305 ok.


I am trying to figure out if 305's will fit or if I should go with the 285/295 setup.
